IMPROVEMENT I N COOKING-STOVES.

` Specification forming part of Letters Patent No. 160,798, dated March16, 1875 5 application filed December '7, 1874. v

.To all whom it may concern:

Be it known that I, ROBERT THOMAS, ot' the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, gentleman, haveinvented certain new and useful Improvements in (looking-Stoves; and Ido hereby declare that the following is a full, clear, and accuratedescription thereof, whereby others skilled in the art might make anduse the same, reference being had to the accompanying drawings and tothis specification.

My invention relates to a class of stoves suitable for all the ordinarypurposes of cooliing and other requirements of the kitchen, and from itspeculiar construction and arrangement requires a small portion only ofthe fuel consumed by other stoves for the performance of the same amountof duty. This stove, when constructed as a summer cooking-stove, is madeof smaller dimensions than when `used throughout the year, and, besidethe saving in fuel, it does not overheat the apartment in which it maybe placed.

The invention consists in making the stove in as few parts as ispracticable, and constructing the lire-chamber so as to give the largestpossible amount of heating-surface.

The chamber is circular, forming, when the tire is lighted up, anincandescent band, radiating heat from both sides. The innercircumference of the band surrounds a dome on the crown of the oven,`and the outer circumference is surrounded by a watervessel or boiler,which gives a constant supply of hot water, and leaves the top of thestove always clear and ready forother culinary or laundry purposes.

In the accompanying drawings the same letters of reference indicate thesame parts in all the views, and in this sl'iecication.

Figure l is a front perspective view of the stove, and showing the watervessel or boiler A, tap M by which the hot water is drawn oif from theboiler, oven-door E and draftdoors P P, the topF with fire-chamber coverH, the raised iiue s, and chimney G. Fig. 2

is a side elevation of stove, showing the water vessel or boiler A, tapM, steam-pipes N N, and draft-doors P P. Fig. 3 is a vertical section,showing the water vessel or boiler A, grate Q, the inner circumferenceof which surrounds the dome O of oven D, and the outer circumference ofwhich is surrounded by the water vessel or boiler A, as previouslyreferred to and described, fire-chamber B, draft-doors P P, top F, andcold-air pipe W. Fig. 4 is a horizontal section through the line a b ofside elevation, showing the plan of oven D and dome O and cold-air pipeNV. Fig. 5 is a ground view of the stove with top F removed in order toshow the position of a rib, R, which is attached to the under side ofcover H, the use of which is to make, by turning the cover H half-wayround, either a direct or a return draft 5 showing also the grate Q andthe position of chimney G. Fig. 6 is asectional plan ofthe dome O,showing the interior ribs r r, Src., which are for the purpose ofstrengthening the dome, and also for the radiation of heat for heating'the oven D. Fig. 7 is aplan of grate Q, which, when in position, issupported on lugs cast on the dome O, which admits of the grate Q beingeasily shaken by a circular motion.

ln the construction of my stove I do not limit myself to any denitenumber of ribs in dome O, nor to the width of openings or thickness ofbars in grate Q, nor to the dimensions of the stove in its variousparts. The stove herein shown and described is about one-eighth of fullsize of a useful summer cooking-stove.

I claim- 1. The combination and described arrangement of the oven D, theannular grate Q surrounding an un perforated dome, the watervessel Asurrounding the tire-chamber, and the top F, as shown and described.

2. The oven D, as constructed with ademe, O, ribbed internally andclosed except at its bottom, and in combination therewith, all as shownand described, and for the purpose set forth.

3. In combination with the oven D, constructed as shown and described,the cold-air pipe W leading into the central oveirheating dome O, all asset forth.

4t. The combination of the draft-doors P P, the top F, adjustableflanged or ribbed cover H, raised iiue S, and its chimney G, all asshown and described.

5. The annular water-vessel A surrounding the annular fire-chamber, andprovided with the tap M and the pipes N N, all combined as shown anddescribed, and for the purposes set forth.
